本発明は、無菌充填系等に於て使用する場合に

菌充填装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sterilization filling device suitable for use in aseptic filling systems, etc., and in particular for continuously high-temperature sterilization of liquid products containing solids while applying a constant back pressure. At the same time, the present invention relates to a sterilization and filling device that can continuously and stably sterilize and fill liquid products without directly applying the above-mentioned back pressure to the filling machine.

には、品質保持の面から、高温短時間で処理する
ことが好ましいとされている。 In general, foods, medicines, etc. undergo spoilage due to microorganisms during storage, so it is widely practiced to sterilize them to a microbiologically safe state before commercializing them. Furthermore, when sterilizing foods and medicines, it is said to be preferable to process at high temperatures and for short periods of time in order to maintain quality.
ところで、製品の殺菌が100℃を超える高温で

沸騰を起こし、これを防止するために殺菌系内に
一定の沸騰抑制圧（以下、背圧と称す）をかけな
がら処理する必要があつた、しかし、この場合
に、従来の方法では下記するような問題があつ
た。 By the way, when products are sterilized at high temperatures exceeding 100℃, the products will boil in the sterilization system under normal pressure, and to prevent this, a certain boiling suppression pressure (hereinafter referred to as back pressure) is applied to the sterilization system. However, in this case, the conventional method had the following problems.
即ち、従来の殺菌系に於る背圧のかけ方の１つ

条件で殺菌することが困難であつた。 In other words, one way to apply back pressure in conventional sterilization systems is to install pumps before and after the sterilizer and control the discharge volume of the two pumps to apply back pressure. Ta. However, in the above method, if the sterilization conditions are such that the product can be sterilized to a microbiologically safe level, considerable high pressure is applied to the rear pump, and product leakage occurs due to the performance of the pump. It is not possible to maintain a constant flow rate and pressure within the sterilizer, which makes it difficult to sterilize products under constant conditions.
また、従来の殺菌系に於る他の背圧のかけ方と

等の問題があり、固形物を含む製品を処理する場
合には、一切使用することができなかつた。 Another way to apply back pressure in conventional sterilization systems is to use a pressure control valve or homogenizer instead of the rear pump in the above case. Do not use this product at all when processing products containing solids that may clog the pressure control valve or homogenizer, causing abnormal pressure within the system and destroying the system. I couldn't do it.

した。 As a result of research aimed at solving the above problem, the present inventors installed a tank in the sterilization system that can control air pressure, and the air pressure controlled by the tank creates a highly stable system. It has been found that it is possible to apply a back pressure essentially and in this case, even if the product contains solids or is highly viscous, it can be processed.

シングを生じる等の問題が発生した。 In addition to the above-mentioned problem of applying back pressure, another major problem in the sterilization system was related to the filling machine. In other words, the filling machine part of the sterilization system generally has relatively low pressure resistance, and it is mechanically undesirable for this part to be subjected to the same pressure as the sterilizer, and when actually filling the product, The filling amount may become uneven, the product may leak from the filling valve of the filling machine due to high pressure and "just liquid", or the product may blow out violently when the filling valve is open. Problems such as so-called flashing occurred.

続的に行なう点では問題があることを知つた。 In addition, in order to prevent the above-mentioned problem from occurring, the present inventors have added on-off valves, etc. to the sterilizer, the back pressure tank, and the filling machine in the above-mentioned back pressure device, which they discovered as a result of their research. With the on-off valve closed, the sterilized product is collected in the back pressure tank, the pressure inside the system is reduced, the on-off valve is opened, and the product is transferred to the filling machine. We considered ways to send it to However, in this case, sterilization and filling of the product are performed completely separately, and it has been found that there is a problem in continuously processing the liquid material.

知つた。 In addition, as another method, if a pressure control valve (safety valve) or a transfer pump is installed between the back pressure tank of the sterilization system and the filling machine, the part behind the pressure control valve or pump of the system The pressure is returned to normal, and back pressure is no longer applied directly to the filling machine. However, the use of a pressure control valve causes problems such as if the product contains solids, the solids will clog this area, causing pressure abnormalities within the system and destroying the system. Also,
When using a pump, it is effective for processing products containing solids to some extent, but the solids are easily destroyed by passing through two pumps, the forward pressure pump and the above pump, and the diameter of the solids increases. I learned that it is unsuitable for processing products containing large solids.

That is, the first object of the present invention is to continuously sterilize a liquid product containing solids at high temperature while applying a constant back pressure, and at the same time to prevent excessive pressure from being applied to the filling machine section. It is an object of the present invention to provide a sterilization and filling device capable of continuously and stably sterilizing and filling. Another object of the present invention is to provide a sterilization and filling device that does not destroy the solids contained in the liquid product and can process even liquid products containing large diameter solids.

非常に安定的に背圧をかけることが可能なこと。 The present inventors conducted research on a sterilization filling device in order to achieve the above object, and as a result, they obtained the following knowledge. That is, the present inventors installed a pressure pump in front of the sterilizer and a back pressure tank, a pressure buffer tank, and a filling tank that can control air pressure in the sterilization and filling device, and (1) First, , the product is sent to the sterilizer by a pressure pump, and while back pressure is applied to the sterilizer by air pressure controlled by the back pressure tank, the product after sterilization is collected into the same tank, (2) the back pressure tank The internal pressure of the pressure buffer tank provided further back is controlled to be the same as or slightly lower than the internal pressure of the back pressure tank, and the product is transferred from the back pressure tank to the pressure buffer tank. After cutting off the pressure buffer tank to reduce the internal pressure of the pressure buffer tank, open the space between the pressure buffer tank and the rear filling tank, and transfer the product from the pressure buffer tank to the filling tank. (4) After the operations in (1) to (3) above, when transferring the product to the filling machine, the sterilizer is equipped with air pressure controlled by a pressure pump and a back pressure tank.

During this time, it was found that by repeating the operations (2) to (4) above, it was possible to stably and continuously fill the product without placing the filling machine under harsh conditions. At the same time, the present inventors have discovered that in the above case, even if the product contains solids with large diameters, the solids can be processed without being damaged.

る。 The product sent to the heater 3 is heated by the heater 3 to, for example, 130 to 150°C. After heating, the holding tube 5 is used to maintain the predetermined temperature and temperature required for sterilization.
The product held for a period of time is cooled to below 100°C in a cooler 4 and then sent to a back pressure tank 6. here,
As the cooler 3, a surface scraping type heat exchanger, a plate type heat exchanger, a tube type heat exchanger, etc. are used. In addition, the back pressure tank 6 is connected to the pressure sensor 1.

閉弁１２は必ず閉鎖の状態にある必要がある。 Next, the products sterilized as described above are sequentially collected into the back pressure tank 6. The product collected in the back pressure tank 6 has the internal pressure of the pressure buffer tank 7,
After controlling the pressure to be the same as or slightly lower than the internal pressure of the back pressure tank 6, the on-off valve 11 is opened and the pressure is sent to the pressure buffer tank 7. Here, the pressure buffer tank 7 is basically the same as the above-mentioned back pressure tank 6, and is equipped with a pressure sensor 14 and a pressure controller 15 (or an air regulator). It has a function. Also,
The product can be transferred from the back pressure tank 6 to the pressure buffer tank 7, for example, by positioning the pressure buffer tank 7 below the back pressure tank 6, by gravity of the product, or by the pressure buffer tank 7. This is done by controlling the internal pressure of the tank 6 to be slightly lower than the internal pressure of the back pressure tank 6.

When a certain amount of product has been collected, the on-off valve 11 is closed, and the internal pressure of the pressure buffer tank 7 is reduced to, for example, normal pressure to about 0.8 kg/cm 2 , and the internal pressure of the filling tank 8 is pressure buffered. Control the internal pressure to the same or slightly lower than the internal pressure of the tank. Next, the on-off valve 12 is opened, and the product is sent from the pressure buffer tank 7 to the filling tank 8. The filling tank 8 is basically the same as the back pressure tank 6 described above, and is equipped with a pressure sensor 14 and a pressure controller 15 (or an air regulator), and has a stirring function if necessary. In addition, as mentioned above, when controlling the internal pressure of the pressure buffer tank 7 and the filling tank 8, it is necessary to control the internal pressure to a level slightly higher than normal pressure using sterile air in order to maintain a sterile state inside the device. preferable. Further, the product is transferred from the pressure buffer tank 7 to the filling tank 8 by the gravity of the product or by the pressure difference between the two tanks.
